The actuator arm apparatus may be installed at one or more stations of the swing-arm machine and used simultaneously with a swing-arm also installed at the same station for depositing both a first item and a product into the raceway at the station, as the swing arm shaft pivots from the rear to the front, and the front to the rear angular positions respectively of the swing arm shaft.
